The classic SILCA 25.1 gasket has been replaced after more than 20 years in the market. The new 252 gasket utilises a high tech and very red, fully synthetic elastomer base material rather than a carbon black filled natural rubber of previous designs.
This unique bright red gasket borrows from industries which require air-tight seals in the harshest of environments, and tests to a life expectancy of more than 5X the carbon filled rubber or Buna-N materials used previously.
In tests with a major disc wheel manufacturer, the new SILCA CP1 Disc Wheel Adapter with 252 gasket literally blew away the field by posting a blow-off pressure of 393 psi where other designs were unable to reach 120psi.
